BUCKLE Specification of Letters Patent.

Patented July 21, 1908.

Application filed. September 25, 1906. Serial No. 336,200.

To all 'whom it may concern:

Be it known that I, LEVY MAYBAUM, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Buckles and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to y theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

This invention has reference generally to improvements in that class offastening or holding devices commonly known in the art as buckles, thesame being used with trunkstraps, shawl and other straps, or belts andcomprising a main frame or body to which one end of the strap ispermanently secured, and a pivotally arranged engaging and retainingclasp or jaw constructed to engage with another portion of the strap tosecure it in any one of its adjusted positions in iirm and positivebinding and holding engagement with the main frame or body of thefastening or holding device.

My present invention, therefore, has for its primary object to provide anovel and simply constructed fastening or holding device, in the form ofa buckle, with a view of providing an effective locking or holding meansfor retaining the grasping or clamping jaw of the buckle at all times inits positively engaged relation with the strap, and one which whenclosed upon the strap will be in such clamped engagement without anytendency to tear or sli A further object of this invention is to providea novel construction of buckle in which the pivotally arranged clampingor grasping element of the device is provided with a rearwardlyextending lever or arm which is of such a construction that when thebuckle is used with the two end-portions of a strap, and firmly pulledabout a body or package, the

pressure of the looped end-portion of the stra which is permanentlyattached to the buc {le-frame, will be in an upward direction againstthe under side of the end of said rearwardly extending lever or arm,thereby forcing the opposite graspin or clamping end of the devicefirmly in its olding or clam ing relation with the opposite end-portionof the strap.

A still further obj ect of this invention is to provide a claspingbuckle, that is one in which the ordinary tongue and the perforations orholes in` the strap are dispensed with, in which the -movable parts ofthe buckle are arranged in such a manner that they can not becomedisengaged to loosen the strap, when arranged around a package, and whenstruck by another package, as in traveling when placing one trunk uponanother.

Other objects of this invention not at this time more particularlymentioned will be clearly understood from the following detaileddescription of the same.

With the various objects of my present invention in view, the sameconsists primarily in the novel buckle hereinafter set forth; and,furthermore, this invention consists in the various arrangements andcombinations of the parts, as well as in the details of the constructionof the same, all of which will be fully described in the accompanyingVspecification, and then nally embodied in the clauses of the claimswhich are appended to and which form an essential part of thisspecilication.

The invention is clearly illustrated in accompanying drawings, in whichFigure l is a plan'view of a buckle embodying the principles of thisinvention, the same being shown in use with a strap, one end of which ispermanently attached to a portion of the buckle, and the otherend-portion of the strap being detachably secured by means of the novelclamping means of the buckle; and Fig. 2 is a side view of the buckle,the same being made on an enlarged scale, and showing in connection withthe same, the two end-portions of the strap. Fig. 3 is a centrallongitudinal vertical section of the various parts of the buckle and theend-portions of the strap, all made on an enlarged scale, and showingthe parts of the buckle in their clamped or holding engagement with thestrap; and Fig. 4 is a longitudinal vertical section taken on line 5 5in said Fig. l showing the clamping or holding means of the buckle inits disengaged relation with the strap. Fig. 5 is atransverse section,taken on line 5 5 in the same figure, both sections being made on anenlarged scale.

Similar characters of reference are employed in all of the abovedescribed views, to

indicate corresponding parts.

Referring now to the said drawings, the reference-character 1 indicatesthe complete CII buckle, thev same comprising an open frame or bodyconsisting of a pair of longitudinally extending side-members or bars 2,the rear end-portions of which are preferably slightly curved in anupward direction as at 8, and are connected by a laterally extendingconnecting member or bar 4. At their forward ends the said side-membersor bars 2 are connected by a laterally yextending member 5 which isformed with an upwardly projecting portion, substantially as illustratedin the Several igures of the drawings. A-cross-bar 6 extends across theopen space between said side-members or bars 2, said bar being for thepurpose of having arrangedabout it, in any usual manner, the loopedend-portion 8 of a strap 7. Another cross-bar or rod 9 is also provided,said cross-bar or rod extending across the open portion between the twoside-members 2, in the manner clearly illustrated. Pivotally arranged orhinged upon said bar or rod 9, by means of the ears or loops 11 is aplate-like body 10, the same being provided at its forward and laterallyextending marginal edge-portion 12 with suitably disposed grasping teethor serrations 13, located in close proximity to the inner face 14 of theupwardly extending member 5. Extending rearwardly from said plate-likebody 10 is a lever or arm 15, the same being rovided with a convexportion 16 and a downwardly and rearwardly projecting concaveend-portion 17, the under surface 18 of which at alltimes lies directlyupon the upper surface of the looped end-portions 8 of the strap 7, inthe manner clearly illustrated in the several figures of the drawings.Said plate-like body 10 is provided upon its marginal and longitudinallyextending edges 19 with upwardly and outwardly extending extensions 20forming suitable iingerpieces, for the purposes to be presently morefully described.

Having thus described the general construction of the various parts ofthe buckle, I will now brieiiy set forth the manner of using the same.

The looped end of the strap having been permanently secured to thecross-bar or rod 6, said strap is placed about the trunk, parcel, apackage, or other body, and the free endportion of the strap passedbeneath the member 5 and along the inner face of the upwardly projectingportion of said member, and directly in front of the toothed or serratededge of the plate-like body 10. As soon as the belt or strap has beenpulled, by means of its free end-portion with sufficient tightness aboutthe trunk'or other package, the looped end-portion 8 of the strap 7 willbegin to bear directly against the under surface 18 of the end-portion17 of the lever or `arm 15, and will immediately exert a pressure uponsaid surface, so that the arm or lever 15 moves in a direction away fromthe outer face of the kbuckle-frame. In this manner a pivotal movementof the plate 10 is produced, -with a consequent downward movement of thetoothed or serrated edge 13 of said plate toward the face of the strap,whereby 'the teeth or serrations enter into a iirm and positive holdingengagement with the strap. Thus the greater the pull upon the freeend-portion of the strap, the greater will be`the pressure which isexerted by the looped portion of the strap against the under surface ofthe end-portion of the lever or arm 15 and hence, the teeth at the otherend of the plate 10 will grasp with greater force the face of the strap,and hold it against displacement.

To release the strap from its tightened position about the package, allthat is necestheir holding engagement with the strap, the fcompressibility of the looped end of the strap being such that theend-portion 17 of the arm or lever 15 is pressed slightly into said looed end-portion of the strap, substantia ly as illustrated in Fig. 4 ofthe drawings. In this manner, the forward and serrated end-portion ofthe plate 10 is slightly and sufiiciently moved in an upward direction,that the strap is clear of the teeth, and can be easily loosened fromits previously tightened relation about the package. It will be noticed,furthermore, from an inspection of the drawings, that the centrallydisposed and convex portion 16 of the lever or arm 15, has a two-foldpurpose; namely, it causes the free end-portion 17 to bear more directlyupon the upper surface of the looped endportion of the strap, and itfurthermore acts as a reinforcing or strengthening means to the device,guarding against any damage to the parts by the coming in contacttherewith of other heavy bodies while traveling.

From the foregoin description of my present invention it wilI be clearlyunderstood that I have devised a simply constructed and effectivelyoperating buckle for trunk and other straps, or, for belts; and onewhich will always be tight when in use, and cannot accidentally becomedisplaced or loosened.

I claim:

1. A buckle for trunk-straps and the like,y comprising a buckle-frameand a clamping plate pivotally connected with said frame, means on saidframe to which one end of a strap can be attached, and a lever extendingrearwardly from said clamping plate, said lever having an outwardlyconvexed portion and a downwardly and rearwardly extending end-portion,said end-portion` being adapted to restdirectly upon the fastenedend-por- 'tion of the strap, so that the upward pressaid lever in anoutward direction from the face of the buckle-frame, and the graspingend of the clamping plate in a direction toward said frame for graspinga portion of the strap, substantially as and for the purposes set forth.i

2. A buckle for trunk-straps and the like, comprising an open of a pairof longitudinally extending siderneinbers, and laterally extending endrnernbers connected with said side-members, a cross-bar between saidside-members to which one end of a strap is adapted to be at tached, across-rod between said side-inembers, a clamping plate, said plate beingprovided with perforated ears arranged on said cross-rod, and a leverextendin rearwardly from said clamping plate, said lever having itsrearward and free end-portion adapted to rest directly upon the fastenedend-portion of the strap, s0 that the upward pressure of the strap willforce the end-portion of said lever in an outward direction toward saidframe for rasping a portion of the strap7 substantially as and for thepurposes set forth.

3. A buckle for trunk-straps and the like, comprising an openbuckle-frame consisting buckle-frame consisting.

of a pair of longitudinally extending sidernernbers, and laterallyextending end-members connected with said side-members, a cross-barbetween said side-members to which one end of a strap is adapted to beattached, a cross-rod between said side-members, a clamping plate, saidplate being provided with perforated ears arranged on said crosserod,and a lever extendin rearwardly from said clamping plate, said everhaving an outwardly convexed portion and a downwardly and rearwardlyextending end-portion, said endortion being adapted to rest directlyupon t e fastened'end-portion of the strap, so that the upward pressureof the strap will force the end-portion of said lever in an outwarddirection from the face of the buckle-frame, and the grasping end of theclamping plate in a direction toward said frame for graspin a portion ofthe strap7 substantially as and for the purposes set forth.

In testimony, that I claim the invention set forth above I havevhereuntoset rny hand this 22nd day of September, 1906.
